ing is a specification.

This invention relates to egg heaters and v devices of a, similar natureadapted to be used to mix liquid and semi-liquid food substances, andhas for its object the production of a device which will be effective inoperation and at the same time may be cheaply constructed.

The invention consists of certain novel features of construction andarrangement of parts which will be fully understood by reference to thedescription of the drawings and to the claims hereinafter given.

Of the drawings: Figure 1 represents an elevation, partially in section,of a beater embodying the features of the present invention. Fig. 2represents an inverted plan of the same. Fig. 3 represents a horizontalsection of the same, looking downwardly, the cutting plane being on line3 on Fig. 1. Fig. 4 represents a horizontal section of the same lookingupwardly, the cutting plane being on line 4 l on Fig. 1, and Fig. 5represents a plan of the upper end of the same.

Similar characters designate like parts throughout the several figuresof the drawin s.

Tn the drawings, 10 is a base plate preferably curved upwardly, asindicated in Fig. 1 of the drawings. This plate is provided. with aplurality-of perforations 11 therethrough through which the material isadapted to pass when the device is being positioned in a receptaclecontaining a substance or substances to be stirred or mixed. This baseplate 10 is so riveted to the end of the threaded shank 12 of a squaredrod 13 that said plate 10 and rod 13 are adapted to be revolved relativeto one another, while the separation of the plate from the shank isprevented.

The upper end of the rod 13 is twisted as indicated at 1 1. Mounted uponthe upper end of the twisted portion 14 is a reciprocating member orhandle 15 having secured to its lower end a plate 16 provided with acentral square perforation 17 fitting the twisted portion of the rod 13.It is obvious that ;when the handle 15 is grasped in the hand andreciprocated lengthwise of the rod 13 the perforated disk 16 will actupon the twisted portion 14: of the rod '13 to rotate it in onedirection during the downward movement of said handle and in theopposite di rection during its return movement. Normally the handle 15is positioned around the upper end of the threaded portion 14 of the rod13, being held in this position by means of the spring 17 one end ofwhich is secured to the upper end of the rod 13 by means of the screw18, while the lower end is secured to the disk 16 at 19. The downwardmovelment of the handle 15 is limited by stop pins 20. The threadedshank 12 extends through a central perforation in the flat conicalspiral member 21 the central portion of whichis clamped to the rod 13 bymeans of a nut 22. This spiral member 21 is provided with a plurality ofupwardly extending projections 23 atthe base of each of which is aperforation 24 through which the material being mixed is adapted to passwhile the member 21 is being oscillated. When the base of the device isbeing placed in the cup or saucer the material contained therein isadapted to freely pass through the perforations 11 in the base plate 10.

When the base plate has been positioned in the bottom of the receptaclethe operator grasping the handle 15 reciprocates the same along thetwisted portion 14 of the rod 13. This causes the rod 13 to beoscillated about its axis moving the spiral mixing member 21 first inone direction and then the other. Owing to the shape of this mixingmember 21 and the projections 23 thereon, the food substances in thereceptacle are thoroughly mixed during the oscillations of the mixingmember. This mixing is facilitated by means of a plurality of upwardlyextending projections acting against the food substances at differentlevels and by means of the perforations at the base of these projectionsthrough which the material is forced to pass during the oscillation ofsaid member. This makes a very simple construction of egg beater whichmay be manufactured at very small expense, while at the same time it isvery effectual in It is believed that the operation and many advantagesof the invention will be fully understood from the foregoingdescription.
